FFM,

I'd pretty much echo what Koala said. I've now had four bouts of ON since 2002 - three in my left eye, one in my right. I'm currently having the sharp, stabbing eye pain and some blurriness in my right eye on occasion and of course, I'm trying to ignore it and chalk it up to eye strain from reading by flashlight for a week when we had no power. I have a follow-up visit to my optometrist on Monday so I'll be discussing it with him if it's still acting up.

You might want to consider a trip to the doctor, just to be safe.
